I am having problems getting ChrisTweak to adjust the Pre-filtering settings for my Hauppauge PVR-150 with drivers of recent vintage. I know this because if you untick the dynamic spatial filtering, and adjust the strength fully to the right, the picture should be extremely blurry. It is not. Further, none of the controls seem to have any effect at all. I have a set of drivers from late 2004 that work fine with CT, however BeyondTV requires the latest drivers, which are listed here: Windows Drivers for PVR-150 If I use the old driver with BTV, the recording job will continue indefinitely, and the application freezes.

I have this problem in both Windows XP and Vista, and always with the new drivers. The native Vista drivers seem to resist control as well.

Are you aware of a workaround, or new drivers that will work with ChrisTweak? Or do you plan to address this problem? I've been using ChrisTweak since the beginning through version 1.80, and since I discovered this problem, none of the recent updates have seemed to cure the trouble.
